1,044,631. p cifi ti of Letters Patent Patented Nov. 19, 1912. Application filed September 17, 1910. Serial No. 582,432. To aZZ whom it may concern: through a pipe I extending to and entering the top of the condenser, where it connects with a pipe K extending downward cen trally through the condenser. New Jersey, have invented certain new and useful Improvements in Jet-C fully described and represented in the folowing specification and the accompanying drawings, forming a part of the same.

his invention relates particularly to jet condensers of that class employing a centrifugal discharge pump and sometimes r from the updenser and carried by the downward through pipe K. Within the ejector e is shown and ref- 1 pipe dperforated with applied with discharge pumps ofother forms, the object of the invention being to provide simple and efficient means for removing the air and uncondensed .vapor from the condenser.

In the accompanying drawings forming a the invention is part of this illustrated as applied in its preferredform, a counter-current conopenings 2, through the pipe (2! collecting above the The pipe K at its lower end is continued b elbow pipe K to the other side of the tail pipe C, and delivers to a centrifugal pump having the impeller g,'preferably mounted on the shaft 0 of pump F, so that the same shaft drives the impellers of the three centrifugal pumps.

It will be understood that the invention is applicable to injector or jet condensers gen erally including parallel flow condensers as well as counter-current condensers,.and that various modifications may be made in carrying out the invention.

at I claim is 1. The combination with a jet condenser and its condensing water supply and discharge pipe, of a liquid ejector within the it air and unconan ejectondischarge pipe, and
